Collection: Fusebox MCBs ( B Type / C type )

Shop FuseBox B-curve and C-curve miniature circuit breakers for compatible consumer units and distribution boards. The range includes single-, double- and triple-pole MCBs across common current ratings, with 6kA and 10kA breaking-capacity options for domestic, commercial and light industrial circuits.

B-curve breakers are commonly used for general circuits with lower inrush currents, while C-curve devices suit equipment with moderately higher start-up demand. Check the amperage, curve, number of poles, breaking capacity and compatibility with your board before ordering. Circuit protection should be selected and installed by a qualified electrician.
